FFB progress
 

Well, the discovery of calibration problem sped things up. Now I am
having consistant results. I found out that Centering Spring should be as a
result of multiplication of Overall and Spring/Dapmer (if those two are
equal). So, for example, these settings are balanced: 125/80/80/100,
80/125/125/100, 125/100/100/125, 100/125/125/125. Centering Spring is the
key of FFB, if you have this right, the rest is easy.
So, it looks like I am almost done. Only have to decide which one is
"the right", 105/100/100/105, or 105/105/105/110. The first one feels just
right, only it is a bit skiddy (maybe because of latency). The second one is
like safer to drive. I'll see, have to test it on different cars, and put it
through some tricky situations, and to see which one is faster, didn't have
time to do that today.
Ah, life is beautiful, : ).

Ok, the story.
It all revolves around Centering Spring (CS). It should be at 100%.
If it is less than that, it is too "free", if it is more than that, it is
too tight. You can have it at 1% less (99%) to "free" setting a bit, or at
1% more (101%) to have more "bite", but I wouldn't move for more than 1%.
100% should be "the neutral" position.
Damper (D) and Spring (S) should be the same. Multiplying Overall
(O) and D/S should give you the value of CS. This means that one can choose
settings from 150/67/67/100 all the way to 67/150/150/100. Overall 150% is
very strong, but it has no slack. Diminishing Overall and adding S and D
will produce slack (probably D is responsible for this). Wheel is most
sensitive at setting O=150 (even too much sensitive), and much less
sensitive at O=67. If you start with O=150 slack starts somewhere at 135,
and Damper is felt at 125 and belov, giving more and more slack and damping.
You can be fast with settings around 105% (with slack), and here it is where
the strength is OK. But maybe it is better to use 135% or something (the
sweet spot, regarding sensitivity), and diminish strength in sim. I was very
fast with 136% or something.

Good news Mario. I'm glad you're happy with the results.

Yes, I am, : ).

Ok, it looks like things are simple. You simply put Overall where
you want it, Spring and Damper where you want it (those two must be equal),
and then calculate Centering Spring by mutliplying Overall x Spring/Damper.
Since prefered position of Spring and Damper probably is 100%, so, you only
have to move Overall, and put Centering Spring at the same value as Overall.

Hm, suddenly everything works like advertised, at least with Skippy
at Watkins Glen. No need for witchcraft. Put Overall where you like, put
Spring and Damper at 100%, and Centering Spring at 50% (probably).
I only have to see if this works on other cars too.
